Inertia and restoring forces can, with low friction or damping, lead to oscillations and resonance. We analyse the mechanics of vibrations.

How we are affected by the very widespread manifesations of diffraction.

A presentation showing how to measure the speed of sound over a short distance on a laboratory table.

A short clip showing the measurement of the speed of sound over short distances.

Dr. Tonomura is a world renowned pioneer and authority in the field of electron holography, for which he has received many national and international recognitions. He is recognized for his contributions in the development of electron holography, the ....

Since the time of Faraday lines of force in space have been 'observed' by sprinkling iron filings around magnet. The lecturer explains how, with modern techniques we can 'see' lines of force inside a solid magnet. The studies reveal a fascinating dyn....

No 10 of ten talks examining the formation of the USA and its early development - from an English point of view. This episode shows how England and the USA have both increased their populations by waves of immigrants from many different areas.

Some heart arrhythmias are produced by the presence of additional pacemakers in the heart. Those pacemakers are death tissues or scars that trap electrical waves. As an analogy, we pinned scroll waves to obstacles using the Belousov-Zhabotinsky react....

Abstract: 21st century chemistry is slowly expanding its concepts into the realm of supermolecular phenomena. However, few tools exist for explaining, creating and controlling complex macroscopic structures and dynamics. In this talk, I discuss our....
